GENERAL DESCRIPTION The device is a single chip PLL frequency synthesizer designed for TV and VCR tuning systems. The circuit consists of a divide-by-eight prescaler with its own preamplifier, a 15-bit programmable divider, a crystal oscillator and its programmable reference divider, a phase/frequency detector combined with a charge-pump which drives the tuning amplifier, including 33 V output. Three NPN open-collector outputs are provided for band switching together with five open-collector NPN outputs. Four of these ports can also be used as input ports (one ADC and three general purpose I/O ports).

TSA5523M
An output is provided to control a Philips mixer/oscillator IC controlled by bits P7, P5 and P4. Depending on the reference divider ratio (512, 640 or 1024), the phase comparator operates at 3.90625, 6.25 or 7.8125 kHz with a 4 MHz crystal. The lock detector bit FL is set to logic 1 when the loop is locked and is read on the SDA line (status byte) during a read operation. The ADC is available for digital AFC control. The ADC code is read during a read operation on the I2C-bus. The ADC input is combined with the port P6. In the test mode, this port is also used as a test output for fref and fdiv/2 (see Table 4). In addition, the circuit includes a DC/DC converter driver connected to the IDC pin to control the amplitude of an external oscillator followed by a voltage rectifier. The voltage rectifier is used to generate the correct tuning supply voltage to maintain a constant current into the tuning amplifier. The DC/DC converter driver can be disabled by setting the IDC pin to VCC1 in this event the tuning supply voltage is delivered by a fixed 33 V supply. Five serial bytes (including address byte) are required to address the device, select the VCO frequency, program the ports, set the charge-pump current and set the reference divider ratio. The device has four independent I2C-bus addresses which can be selected by applying a specific voltage on the AS input (see Table 3). APPLICATIONS * Multimedia TV tuners and front-ends * VCR tuners.

FUNCTIONAL DESCRIPTION The device is controlled via the two-wire For programming, there is one module address (7 bits) and the R/W bit for selecting the read or the write mode. Write mode: R/W = 0 (see Table 1) After the address transmission (first byte), data bytes can be sent to the device. Four data bytes are needed to fully program the device. The bus transceiver has an auto-increment facility which permits the programming of the device within one single transmission (address + 4 data bytes). The device can also be partially programmed providing that the first data byte following the address is Divider Byte 1 (DB1) or Control Byte (CB). The meaning of the bits in the data bytes is given in Table 1. I2C-bus.
TSA5523M
The first bit of the first data byte transmitted indicates whether frequency data (first bit = 0) or control and ports data (first bit = 1) will follow. Until an I2C-bus STOP condition is sent by the controller, additional data bytes can be entered without the need to re-address the device. The frequency register is loaded after the 8th clock pulse of the second Divider Byte (DB2), the control register is loaded after the 8th clock pulse of the control byte and the ports register is loaded after the 8th clock pulse of the Ports Byte (PB). I2C-bus address selection The module address contains programmable address bits (MA1 and MA0) which offer the possibility of having several synthesizers (up to 4) in one system by applying a specific voltage to the AS input. The relationship between MA1 and MA0 and the input voltage on the AS input is given in Table 2.

Data can be read out of the device by setting the R/W bit to logic 1. After the slave address has been recognized, the device generates an acknowledge pulse and the first data byte (status byte) is transferred on the SDA line (MSB first). Data is valid on the SDA line during a HIGH level of the SCL clock signal. A second data byte can be read out of the device if the processor generates an acknowledge on the SDA line (master acknowledge). End of transmission will occur if no master acknowledge occurs. The device will then release the data line to allow the processor to generate a STOP condition. When Ports P0 to P2 are used as inputs, the corresponding bits must be logic 0 (high-impedance state). The Power-On Reset flag (POR) is set to logic 1 at power-on. It is reset when an end-of-data is detected by the device (end of a read sequence). Control of the loop is made possible with the in-lock flag FL (FL = 1) which indicates when the loop is locked. The bits I2, I1 and I0 represent the status of the I/O Ports P2, P1 and P0 respectively. A logic 0 indicates a LOW level and a logic 1 indicates a HIGH level (see threshold level in the "Characteristics"). A built-in ADC is available on pin P6. This converter can be used to feed AFC information to the controller from the IF section of the television. The relationship between bits A2, A1 and A0 is given in Table 9. At power-on, the device is reset as follows: all ports are set to the high-impedance state, except P4, P5 and P7 which are set to logic 1. The tuning amplifier is in the high-impedance state (OS = 1). The POR level is fixed to 3 x VBE (2.1 V typ.). If VCC1 goes below the POR level the circuit is reset.

APPLICATION INFORMATION Tuning amplifier The tuning amplifier is able to drive the varicap voltage without an external transistor. The Vtune output must be connected to an external load of 27 k connected to the tuning voltage supply. Figures 6 and 7 illustrate a possible loop filter. The component values depend on the oscillator characteristics and the selected reference frequency.
Crystal oscillator The crystal oscillator uses a 4.0 MHz crystal in series with an 18 pF capacitor. The crystal operates in the series resonance mode. The connection to VCC1 is preferred, but it can also be connected to GND.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all SSOP packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering Wave soldering is not recommended for SSOP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices.
TSA5523M
If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow and must incorporate solder thieves at the downstream end. Even with these conditions, only consider wave soldering SSOP packages that have a body width of 4.4 mm, that is SSOP16 (SOT369-1) or SSOP20 (SOT266-1). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
